languagedetection

Ruby Library for the languagelayer API, powerful language detection, https://languagelayer.com/

Offering a uniquely simple way to automate language detection using any programming language, accurate, efficient, and lightning fast.

Installation

Add this line to your application's Gemfile:

gem 'languagedetection'

And then execute:

$ bundle

Or install it yourself as:

$ gem install languagedetection

Configuration

Before using the languagelayer API client you have to setup your account and obtain your API Access Key.
You can get it by signing up at https://languagelayer.com/product.

API Overview

All endpoints in the public API is available through this library.

detect
batch
languages

Usage

The general API is documented here: https://languagelayer.com/documentation.
You can find parameters, result set definitions and status codes documented here as well.

In the examples directory you can find demos and samples of general usage of all the API functions.

Setup

First we require the module

require 'languagedetection'

Second we instantiate the client

@client = LanguageLayer::Client.new( [access_key] )

Required Parameters

access_key

Your unique key that you can find on the dashboard of your account under the languagelayer account.

Optional Parameters

Secure (only available for Basic, Pro and Enterprise accounts)

Boolean value to indicate if the calls to the API should use a secure protocol or insecure (HTTP/HTTPS). Defaults to false (HTTP, insecure).

Detect (simple case)

Takes a query string and detects the language.

Define Query

First we get a reference to the string that needs to be detected

query = 'Good afternoon, sir. How are you today?'

Second we define an options object. All the options are documented here: https://languagelayer.com/documentation

options = LanguageLayer::DetectOptions.new()

Call Client

We then place the actual call to the API, passing in the email we wish to check and the options we defined above.

response = @client.detect( [query] [, options] )

Response

If we pass the email Good afternoon, sir. How are you today? as the query argument above, we get the following result:

{
        "success": true,
        "results":[
            {
                "language_code": "en",
                "language_name": "English",
                "probability": 12.141682269266,
                "percentage": 100,
                "reliable_result": true
            }
        ]
    }

Batch Detection

Takes an array of strings and detects the language with a corresponding list of detections for each string.

Define Query

First we get a reference to the string that needs to be detected

query: [
            'Good afternoon, how are you today?',
            'Guten Tag mein Herr, wie geht es Ihnen?',
            'Buenos días señor, cómo está hoy?'
        ],

Second we define an options object. In this example we are passing the show_query option so each of elements in the result will contain the original query. All the options are documented here: https://languagelayer.com/documentation

options = LanguageLayer::BatchOptions.new({
    show_query: 1
})

Call Client

We then place the actual call to the API, passing in the email we wish to check and the options we defined above.

response = @client.batch( [query] [, options] )

Response

{
    "success": true,
    "results": [
        [
            {
                "query": "Good afternoon, how are you today?",
                "language_code": "en",
                "language_name": "English",
                "probability": 12.141682269266,
                "percentage": 100,
                "reliable_result": true
            }
        ],
        [
            {
                "query": "Guten Tag mein Herr, wie geht es Ihnen?",
                "language_code": "de",
                "language_name": "German",
                "probability": 23.045066185021,
                "percentage": 100,
                "reliable_result": false
            }
        ],
        [
            {
                "query": "Buenos días señor, cómo está hoy?",
                "language_code": "es",
                "language_name": "Spanish",
                "probability": 14.560273752505,
                "percentage": 100,
                "reliable_result": false
            },
            {
                "query": "Buenos días señor, cómo está hoy?",
                "language_code": "pt",
                "language_name": "Portuguese",
                "probability": 13.98519485076,
                "percentage": 96.05035652818,
                "reliable_result": false
            },
            {
                "query": "Buenos días señor, cómo está hoy?",
                "language_code": "gl",
                "language_name": "Galician",
                "probability": 13.585199932687,
                "percentage": 93.30319033562,
                "reliable_result": false
            }
        ]
    ]
 }

Supported Languages

Returns the list of Supported Languages, similar to the list found here:
https://languagelayer.com/languages

Define Query

For this endpoint, we dont pass any primary argument, just the control options, so we define an options object. There are currently no options for the languages endpoint, so we could omit it, however we use it with an empty options object here to stay aligned with the standard for the library.

options = LanguageLayer::LanguagesOptions.new()

Call Client

We then place the actual call to the API, passing in the email we wish to check and the options we defined above.

response = @client.languages([options] )

Response

{
    "success": true,
    "languages": [
        {
            "language_code": "en",
            "language_name": "English"
        },
        {
            "language_code": "af",
            "language_name": "Afrikaans"
        },
        {
            "language_code": "ar",
            "language_name": "Arabic"
        },
        ...
    ]
}

Example Application

In the [rootdir]/example directory there is a fully functional application which runs all requests against all the endpoints in the API, the examples above can be seen there as source code.

The example application uses a process.env variable to hold the access key.

Tests

The tests are written using the rspec testing library.
RSpec http://rspec.info/

In order to run the tests, the following environment variables needs to be set:

ACCESS_KEY = [access_key]
